MW.90.10  /  T.1

  • Three (3) P.I.D. settings for acceleration, running, and deceleration—controller maintains consistent tension relative to line speed; does not use an average value.
  • Digital input display and digital output scale to easily monitor the brake or drive being controlled.
  • Ten (10) programmable presets allow easy switching from one material to another.
  • Controller “remembers” optimal running parameters for each situation.
  • Operator-friendly and easy to interface with existing machine controls.

  • Various mounting styles including flange-mounted (CF series), foot-mounted (CB series), through-shaft (CK series), and cantilevered.
  • Full-bridge strain gages improve accuracy by allowing controller to average the input from both load cells. Also, if one load cell malfunctions, the tension control system can still work with an easy recalibration.
  • Integrated mechanical stop protects strain gage; 300% maximum overload.


The CB load cell handles extremely heavy rollers and high tensions. It is not a compressive load cell. Instead, it measures force tangent to the mounting surface so the weight of the roller does not register within the output scale. This design ensures accuracy even under severe conditions.


Amplifiers

Load cell signals should be amplified when the distance from the load cells to the controller is greater than 30 feet, or when signal compatibility with an existing PLC is required.
